Query Services Query Services Object structure services and enterprise services support query operations. An external source can use a service to run a query and to retrieve data from a system. In both cases, the object structure schema defines the XML content for the query request and the query response. For an object structure that has more than two levels of business objects, the query framework supports the use of business object attributes in the top two levels of the request XML. The query response XML contains all the objects in the object structure. All system-provided object structures with a Consumed By value of INTEGRATION, support the query operation by default. You can use the Object Structures application to create additional object structures which provide support for the Query operation. Creating an Enterprise Service Query To create an enterprise service query: 1 If one does not exist, create an object structure containing the objects that the query needs to access. 2 Define an enterprise service that implements the previously created object structure. 3 Specify Query as the operation on the enterprise service. 4 Associate the enterprise service with an external system, and enable the external system and its enterprise service. The system provides a sample query enterprise service, MXINVBALQInterface. Use this sample as a reference when you build query enterprise services. Query Root Element The name of the root element of a query is the concatenation of the operation (Query) and the name of the associated object structure. For example, QueryMXPERSON, where MXPERSON is the object structure. 240 Integration Guide

Query Services

Integration Guide
Query Services
Object structure services and enterprise services support query operations. An
external source can use a service to run a query and to retrieve data from a
system.
In both cases, the object structure schema defines the XML content for the
query request and the query response.
For an object structure that has more than two levels of business objects, the query
framework supports the use of business object attributes in the top two levels of
the request XML. The query response XML contains all the objects in the object
structure.
All system-provided object structures with a Consumed By value of
INTEGRATION, support the query operation by default. You can use the Object
Structures application to create additional object structures which provide
support for the Query operation.
Creating an Enterprise Service Query
To create an enterprise service query:
1
If one does not exist, create an object structure containing the objects that the
query needs to access.
2
Define an enterprise service that implements the previously created object
structure.
3
Specify Query as the operation on the enterprise service.
4
Associate the enterprise service with an external system, and enable the
external system and its enterprise service.
The system provides a sample query enterprise service, MXINVBALQInterface.
Use this sample as a reference when you build query enterprise services.
Query Root Element
The name of the root element of a query is the concatenation of the operation
(Query) and the name of the associated object structure. For example,
QueryMXPERSON, where MXPERSON is the object structure.
